Abstract: A method of running a network application based on a Point-of-Sale (POS) terminal is provided. The method includes: receiving an operation on a network application; calling a first interface of a JAVASCRIPT layer according to the operation; parsing the first interface and acquiring an object corresponding to the first interface; transmitting a corresponding signal through the object and executing a slot function associated with the signal; calling a second interface of a plug-in layer through the slot function, and calling a hardware module corresponding to the second interface to perform the operation. The POS payment terminal traverses and accesses nodes in an object tree through an embedded graphical user interface system according to a node hierarchy relationship in the object tree, and renders various tag objects contained in the object tree one by one to display a network application page on a display screen of the POS payment terminal.
